Hello,

The water from our water tank in the loft keeps overflowing out of the
overflow pipe.

We recently replaced the ball valve and I checked the level at which it
shuts off the water however, the water has started to overflow again?

This is the valve that feeds the tank? If so, that shouldn't have
anything to do with an overflow I would think. If the water is coming out
of the PRV (Pressure Release Valve) than either it's failing or your water
pressure is too high for it. Sounds like either way, the PRV needs to be
replaced you just have to figure out why.
Cheers,

No. This is not a hot water tank or anything of that sort. It is an
accumulator tank (think cistern) which is found commonly in the attics
of older homes in the UK. The valve in question is probably much like
the float valve in the tank of a WC and regulates how full the tank is
refilled.

Thanks for the reples and suggestions - I hadn't thought about the pressure being too high however, shouldn't ball valves be able to withstand mains water pressure?
